             Summary: Add support for Elasticsearch 2.x to upgrade release branch
                 Key: PIO-33
                 URL: https://issues.apache.org/jira/browse/PIO-33
             Project: PredictionIO
          Issue Type: New Feature
    Affects Versions: future release
            Reporter: Pat Ferrel
            Assignee: Pat Ferrel
             Fix For: future release


We have code that does this but the remaining issure is that ES encodes data differently than 1.x and so teh current form of engine.json `sparkConf` does not work. This can be removed as a feature afaik since all of thos params can be passed on the command line. Also we could escape illegal characters in the engine.json and unescape before passing them to Spark.

This will be binary incompatible with ES 1.x so adding to the upgrade branch
